      Merge media fixes from Mauro Carvalho Chehab:
       "This contains two patches fixing problems with my patch series meant
        to make USB drivers to work again after the DMA on stack changes.
      
        The last patch on this series is actually not related to DMA on stack.
        It solves a longstanding bug affecting module unload, causing
        module_put() to be called twice. It was reported by the user who
        reported and tested the issues with the gp8psk driver with the DMA
        fixup patches. As we're late at -rc cycle, maybe you prefer to not
        apply it right now. If this is the case, I'll add to the pile of
        patches for 4.10.
      
        Exceptionally this time, I'm sending the patches via e-mail, because
        I'm on another trip, and won't be able to use the usual procedure
        until Monday. Also, it is only three patches, and you followed already
        the discussions about the first one"

      gp8psk: Fix DVB frontend attach · 7a0786c1
      Mauro Carvalho Chehab authored
      The DVB binding schema at the DVB core assumes that the frontend is a
      separate driver.  Faling to do that causes OOPS when the module is
      removed, as it tries to do a symbol_put_addr on an internal symbol,
      causing craches like:

      iio: maxim_thermocouple: detect invalid storage size in read() · d70674ee
      Arnd Bergmann authored
      As found by gcc -Wmaybe-uninitialized, having a storage_bytes value other
      than 2 or 4 will result in undefined behavior:
      
      drivers/iio/temperature/maxim_thermocouple.c: In function 'maxim_thermocouple_read':
      drivers/iio/temperature/maxim_thermocouple.c:141:5: error: 'ret' may be used uninitialized in this function [-Werror=maybe-uninitialized]
      
      This probably cannot happen, but returning -EINVAL here is appropriate
      and makes gcc happy and the code more robust.
